Title: Ball throwing machine for sports training - using variable movable friction wheel to make ball behaviour controllable and variable, to produce spin effect in all directions
Inventor: REENTS HEINRICH PROF DR ING
IPC: A63B69/40
Filed: 1990-04-27
Abstract: The machine throws out balls for sports training, in which the flight energy of the ball (5) is provided by a single rotating wheel (2) whose rate of revolution can be controlled. It has either a flexible or a rigid surface (4) of a defined shape, to increase friction on the ball, and an opposite, low friction, surface. A spin effect is produced by a variable, controllable decrease in power on the ball surface by a variable, movable friction wheel (27). The system is controlled by use of sensors (33,34,35,37 etc.) and the desired ball throwing combinations can be programmed, remotely, using a connected microcomputer (38). USE/ADVANTAGE - For use in ball sport training e.g. tennis, table tennis, squash, football. Has small size and is light and portable. Enables ball spin in all directions to more realistically simulate actual play. Is fully automatic and programmable and the ball characteristics can be easily varied. Can be connected to other ball machines for coordinated training.

Title: Detecting position of breakage point of reinforcing steel in concrete - applying magnetising field followed by demagnetising field and then measuring relevent magnetisation field
IPC: G01N27/82
Filed: 1990-11-29
Abstract: A method of locating a breakage point in the reinforcing steel of reinforced concrete involves applying a magnetostatic and/or quasimagnetostatic field in the region of the reinforcing steel which is thus magnetised. An electromagnetic demagnetising field is applied to demagnetise the mesh. The magnetic field of the remanent magnetism in the steel is detected and a peak in the field used as a criterion for the breakage point. ADVANTAGE - Enables reinforcing steel breaks to be located even when there is a concrete steel mesh between the reinforcement under investigation and the concrete surface.
Patent DE-4104797-A1 (DE)
Inventor: GOERISCH ARMIN
IPC: F03B15/14
Filed: 1991-02-16
Abstract: The invention relates to a hydro-electric plant in which turbine sets (5, 6, 7) provided with a braking device are employed. The turbine sets are situated in shafts (2, 3, 4) with inlet openings (9, 10, 11) at different levels, which are in turn arranged in a collecting basin (1). The shafts are of open design and allow the liquid to flow in freely. A water level detector (13) which records the water level in the collecting basin (1) releases a braking device of the respectively associated turbine set at water levels assignable to the respective shafts and thus allows them to be put into operation. Similarly, the individual turbine sets are succesively disconnected from the mains with the aid of the braking device from certain respectively assignable and measurable water levels as the level falls. <IMAGE>

Filed: 1991-04-24
Abstract: 2.1. Transport devices for cutting units or the like have hitherto been designed as independent single-axle or two-axle trailers onto which the working implement (10) could be placed. It is a disadvantage that a self-supporting structure involving high costs is consequently necessary. In another known version, an undercarriage is mounted at the front and at the rear end of the working implement (10), this being expensive and increasing the total length of the train. 
<??>2.2. The proposed transport device consists of a connecting rod (24) and of an undercarriage (26), the connecting rod (24) being pushed into the working implement (10) and being fastened there, and the undercarriage (26) being mounted underneath the working implement (10). 
<??>2.3. Transport devices (12) of this type are employed for transporting agricultural implements.

Title: Fodder drying - uses controlled microwave energy and air drying according to moisture level and required residual moisture content
Inventor: EYERLE ANTON
IPC: A23K3/00
Filed: 1991-11-26
Abstract: To prepare and conserve fodder and for harvested material, with a combined microwave and air drying action, the residual moisture of the material is initially measured, and microwave energy is applied sufficiently to break the cell surface structure while the cell fluid is mostly contd. The material is then subjected to low temp. air drying at 70-110 deg.C according to each intermediate moisture level, for most of the moisture in the material to be removed. A determined residual moisture content for the material is set. The heat generated is recovered for further assemblies and preheating of the air dryer. Also claimed is an assembly with an initial moisture meter (6) to read the opening moisture level before the material reaches the microwave drying section (5). After microwave drying (5), the material is carried through a belt air dryer (8). USE/ADVANTAGE - The technique is for the preparation of winter fodder and/or harvested material. The material is dried with min. energy consumption and material while retaining its nutrient value.

Abstract: A coin checking system has a facility for handling three different sizes of coins. Coins are entered and are received by a balanced lever (6) that directs them to a guide track (54). A lever (51) limits the entry to those less than the largest diameter coin. A second lever (60) identifies the difference between the largest and middle size coin. Bar magnets (65,67,68) check each of the sizes. Coins fall onto a stop (70). The trajectory is controlled to direct false coins to the left and into a reject channel. Correct coins are directed to the right channel.  Correct coins are directed to the right. USE/ADVANTAGE - Improved recognition of counterfeit or false coins.

IPC: C12Q1/04
Filed: 1992-05-21
Abstract: The shortage of available iron for the growth of micro-organisms adversely, affects cultivation from materials to be examined like foodstuffs, medico-microbiological samples and from materials to be examined from the environment. The methods currently used capture such micro-organisms and add to them the more extensive characteristics needed for epidemiological research are material and time-consuming and give limited results. This applies especially to the cultivation of salmonella from food samples, which has not yet been successful enough to cover salmonelloses. The addition of iron chelators (microbial siderophores or synthetic iron chelators) as a growth supplement to the material to be examined, and/or the enriching and selective culture substances which can be used by the micro-organisms for their iron supply, makes possible a significant improvement in the cultivation or reisolation of the micro-organisms, both quantitatively (increasing sensitivity) and qualitatively (increasing selectivity). The addition of such iron chelators to micro-organism cultures makes product control possible in bio-technological and genetic engineering processes. The fields of application are medical microbiology, food microbiology, environmental microbial research, biotechnology and genetic engineering. A special field is the improvement of sensibility and selectivity in the cultivation of salmonella investigation materials by the addition of ferrioxamine siderophores, especially ferrioxamine G.
